President-elect Donald Trump's mass deportation plan could face significant hurdles to implement.
"I think he's going to violate every norm and law in order to do what he wants. The question is whether he really is going to have a program as expansive as he's described, because the reality of what he's described would be pretty devastating to the national economy and the workforce," Rep. Veronica Escobar, D-Texas, told The Hill.
Incoming border czar Tom Homan said in an interview that the size of the deportation program would depend on how much money the program gets from Congress.
"I don't have a number. We want to arrest as many people as we can that are in the country illegally," Homan said on CNN.
"If you're here illegally, you're not off the table. It's a violation of the law; it's a crime to enter this country illegally."
Deporting 1 million undocumented immigrants a year would cost $88 billion, according to the American Immigration Council.
"Until we hear from the future president himself whether he plans to deport as many people as he promised, all of this is hypothetical," Escobar told The Hill.
Homan has said he would need 100,000 detention beds and a large increase in border agents at a cost of $86 billion.
Democrats have also vowed to file legal challenges against Trump's plans, including ending birthright citizenship.
"If that is indeed their first executive order, which is what they're talking about, we will have to fight them on that. If they are proposing to do it the right way by amending the Constitution, we will oppose it," said Rep. Jamie Raskin, D-Md.
In Trump's first term, several of his immigration plans faced court challenges and were found to have violated the Administrative Procedure Act, the Hill reported. Other executive orders, including ending protection for Dreamers and using an emergency declaration to fund his border wall, were also struck down by the courts, The Hill reported.
Escobar said he thinks Trump will still find a way to get what he wants.
"I think he's going to trample over the Constitution. I think he's going to trample over existing law. ... I feel like he's going to be violating laws and the Constitution left and right," Escobar said.
